2.2 The Characteristics of the Non-detective Image

She not only created the famous Belgian detective Hercule Poirot and the country detective Miss Marple, at the same time, she also created many non-detective images, such as criminals, showing a variety of different motives for readers. Christie is very good at writing some typical criminal images. Psychological allergy is not her best at the shape of the crime in image. Christie thinks that evil is innate, is caused by the human inner demons, and the background of the times, social environment. Even if it does not in the form of crime, cover-up of crime, psychological metamorphosis, it still exists in the human heart. It is a super-social and time-to-space enemy that can not be finally eliminated. Fundamentally, it is humanity that leads to the motive of crime.

Agatha Christie moved from contingency to inevitability, from a single motive of crime to the common root of human nature. Against the background of evil human nature, she defined the nature of her criminal. Everyone can have a potential motive to kill, so anyone can be a potential murderer. In the Death on the Nile, the murder took place on a cruise ship, and people from all over the world went through three murders in a few days and nights on a voyage. Everyone was full of a sense of crisis, but to leave, he had to wait until the voyage was over. Everyone has a motive to commit a crime, and everyone can be a murderer. In this closed space where people gather, people don’t know who the real killer is, but the killer is real between people, and if you think about it, you will find that everyone has a potential motive to kill, and everyone is likely to be a potential criminal.
